LIQUID CRYSTAL DISPLAY DEVICES AND METHOD FOR PRODUCTION THEREOF

摘要

A matrix addressable liquid crystal display includes a thin film circuit supported on a substrate having a plurality of parallel bit lines. A plurality of individual pixel circuits each include a two terminal bi-directional gate device which is formed from at least one thin film layer with one gate device terminal connected with the associated bit line. A terminal plate is connected in circuit with the other terminal of the gate device. A transparent cover plate is spaced above the thin film circuit with a transparent conductor structure on the underside of the cover plate. The space beneath the cover plate is filled with a liquid crystal display material to form individual display pixel circuits at the terminal plates. A plurality of parallel word lines are arranged orthogonally to, and insulated from, the bit lines. The word lines are connected in circuit with the individual display pixel circuits at the respective cross-overs with the bit lines. The pixel circuits are each operable to change the state of the associated portion of the liquid crystal display material in response to the concurrent application of voltage pulses of opposite polarities to the associated word and bit lines.
